Z4 root issues

I used z4 to root my phone 2 nights ago. Everything appeared to go well. I tried to pull a file from my SD card and there's nothing there. I attempted to find the backup I performed via Bootstrap and again nothing on the SD card.

I then tried to save a new file to the SD card and got a message that the SD card was blank with an option to format the card. Now what? What's going on with my SD card?

Is there any way to get the data back? What do I do to get the SD card to work?
